The 19-year-old Keeping Up With the Kardashians star helped arrange a surprise marriage proposal for her friend and assistant Victoria Villarroel Gamero.

Her boyfriend and soccer player Marco Lobo proposed to her on a platform decorated with candles arranged in a heart shape in Malibu, California Saturday as Kylie and several other friends watched from above.

"@kyliejenner words can't even describe how thankful I am to have you in my LIFE!" Gamero wrote on Instagram, alongside a photo of the two women hugging. "I am OBSESSED WITH YOU."

Kylie documented the aftermath of the proposal on Instagram and Snapchat.
